From today's featured article Astraeus hygrometricus, the false earthstar, is a fungus common in temperate and tropical regions around the world. When young, it resembles a puffball; in maturity, the outer layer of fruit body tissue splits open in a star shape, similar in appearance to the earthstars. The fungus grows in mutual symbiosis with roots of various trees, especially in sandy soils. It can open up its rays to expose the spore sac in response to increased humidity, and close them up again in drier conditions. The rays have an irregularly cracked surface, while the spore case is pale brown and smooth with an irregular slit or tear at the top. The gleba is white initially, but turns brown and powdery when the reddish-brown spores mature. The species was first described by Christiaan Hendrik Persoon in 1801. Several bioactive chemical compounds have been found in the fruit bodies. North American field guides typically rate the fungus as inedible. (Full article...) Recently featured:

Jane Seymour (c. 1508 – 1537) was Queen of England from 1536 to 1537 as the third wife of King Henry VIII. She succeeded Anne Boleyn as queen consort following the latter's execution in May 1536. She died of postnatal complications less than two weeks after the birth of her only child, a son who became King Edward VI on Henry's death. She was the only one of Henry's wives to receive a queen's funeral, and his only consort to be buried beside him in St George's Chapel at Windsor Castle. Painting: Hans Holbein the Younger |
